UNITED STATES PATENT FFICE.

GREGOR TRINKS, OF JERSEY CITY, NEW JERSEY.

WINDOW-CURTAIN SLIDE.

Specification of Letters Patent No. 28,922, dated June 26,1860.

To all whom it may concern.'

Be it known that I, GREGOR TRINKS, of Jersey City, Hudson county, Stateof New Jersey, have invented a new and useful Improvement inWindow-Curtain Slides; and I do hereby declare that the following is afull and exact description thereof.

My invention consists in an improvement in construction and arrangementof the rack and spring catch connected with the sliding cord pulley of awindow curtain slide or fastening.

The object of my invention is to effect the release of a curtain cordpulley slide, which has no other motion than a sliding motion, withoutmaking further tension upon the cord, and simply by pressing down thethumb piece of the spring catch.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation, reference being hadto the annexed drawings, forming a part of this specification, in which-Figure l, is a front elevation of my improvement; Fig. 2, a sidesectional elevation of the same; Fig. 3, a back elevation.

Similar letters of reference indicate the same parts.

A isthe frame of the slide; B, rack upon the edges of the same; C, thumbspring; C thumb piece on same; D, cross piece attached to spring; E,slide piece to which button G, and the spring C, are attached; E', rivetwhich unites spring C, and slide piece E; E, washer; F, friction wheelon the button Gr; H, slot in the frame A.

The frame A, of my improvement is made much in the usual manner, exceptthat it is slotted through its central portions at H, and has rack teethcut on its side parts as shown. The slide piece E is attached to thebutton G, by means of a rivet, the friction roller, F, over .which thewindow curtain cord passes, being secured on the rivet which unites theslide piece E and button G.

The spring C, is furnished at its lower part with a cross piece D, whichfits the rack teeth of the frame. The spring is attached by a rivet E tothe slide piece E, and moves with it. `When at rest the spring serves tohold the cross piece D, against the teeth of the rack, and therebyretains the slide piece E and its appurtenances, in a given position. Aportion of the spring projects through the slot H, to a convenient pointbelow the button G, and terminates in a suitable thumb piece C', thespring with its cross piece and thumb piece when connected with the cordpulley slide being, and performing the function of, a spring catch orlatch. When it is desired to tighten the window cord, the finger isplaced on C', and the spring C pressed inward, which carries back thecross piece D, clear of the rack teeth, and permits the requiredmovement of the slide E, by means of the button G.

My improvement is one of great simplicity, efectiveness, and cheapnessof construction. The objections to the common slides such as theirliability to become worthless, after being a short time in use, and thedanger of wounding the hand, by exposure to the unprotected edges andcorners of the same, in the act of adjustment, are entirely obviated bymy invention, and a safe, convenient and durable slide provided, at areduced cost.

`What I claim as my invention and desire to secure by Letters Patent ofthe United States is- In connection with the slide of a sliding cordpulley, of a window curtain fastening the improved construction andarrangement of the spring latch and double rack substantially asdescribed and substantially for the purposes hereinbefore set forth.

GREGOR TRINKS.
